It's a good book, but Crowe gets caught up repeating questions about movies Wilder either didn't like or the audience probably wouldn't care about. He should've let Wilder talk more about other filmmakers, especially when he was excited to praise them—that would've been way more interesting.
The book is detailed—maybe too detailed—and could've been 50–100 pages shorter. I enjoyed reading most of it, but it didn't really make me want to watch more of Wilder's movies. I also wish Wilder had been given more space to share his thoughts on Hollywood, especially since he made a movie about it!
I'm not sure if some of Wilder's answers were edited out by agreement between him and Crowe, but at times, the follow-up questions felt off, like someone else had stepped in to ask them. Thankfully, Wilder's talent as a good storyteller keeps it engaging.
